Description

本発明は、携帯端末機のアンテナ装置に関し、より具体的には、それぞれ異なる周波数帯に用いられるアンテナを一つのアンテナ装置に具現する装置に関する。   The present invention relates to an antenna device for a portable terminal, and more specifically, to a device that embodies antennas used for different frequency bands in one antenna device.

一般に、携帯端末機とは、ユーザが時間や場所に制約されることなく自由に無線通信、ネットワーク接続、デジタル放送受信などの機能が利用可能な電子機器である。携帯端末機において、アンテナは無線通信を円滑にするための必須要素である。アンテナとは、無線通信において、通信の目的を達成するために電磁波を空間へ放出するか又は吸収するための装置である。アンテナは、使用周波数または波長によって種々の形を有する。アンテナを效率的に動作させるためには、アンテナを使用周波数において共振させなければならない。   In general, a portable terminal is an electronic device that allows a user to freely use functions such as wireless communication, network connection, and digital broadcast reception without being restricted by time or place. In a portable terminal, an antenna is an essential element for facilitating wireless communication. An antenna is a device for emitting or absorbing electromagnetic waves into space in order to achieve the purpose of communication in wireless communication. The antenna has various shapes depending on a use frequency or a wavelength. In order for the antenna to operate efficiently, the antenna must resonate at the operating frequency.

近年の携帯端末機は、携帯を容易にしかつデザイン性を高めるためにサイズが小型化しつつある。それに、機能的には複合化して無線通信は勿論のこと、無線インターネット通信、ナビゲーション機能、デジタル放送受信機能、及びブルートゥース機能などが付加されている。それにより、周波数帯はさらに細分化され、一つの携帯端末機に使用周波数帯も２〜３個に増えている。   In recent years, the size of portable terminals has been reduced in order to facilitate portability and enhance design. In addition, it is functionally combined with wireless communication, wireless Internet communication, navigation function, digital broadcast receiving function, Bluetooth function, and the like. As a result, the frequency band is further subdivided, and the frequency band used for one mobile terminal is increased to two or three.

使用周波数帯の数が増加するに伴い、それに必要なアンテナの数も増えるようになる。用いられるアンテナの数が増加すると、携帯端末機のサイズが大きくなるという問題が生じる。   As the number of frequency bands used increases, the number of antennas required for the frequency band increases. As the number of antennas used increases, the size of the mobile terminal increases.

このような問題を解決するために、近くの周波数帯に用いられるアンテナを単一化している。しかし、互いに異なる周波数帯に用いられるアンテナは、単一化が困難であり、それぞれの周波数帯に用いられるアンテナを別途に実装しなければならないという問題がある。   In order to solve such problems, antennas used in nearby frequency bands are unified. However, it is difficult to unify antennas used in different frequency bands, and there is a problem that antennas used in the respective frequency bands must be separately mounted.

すなわち、従来の携帯端末機では、一つの携帯端末機において、周波数帯の異なる複数の通信信号を送受信するために、それぞれの周波数帯に用いられるアンテナを個別的に具備しなければならない。例えば、一つの携帯端末機でデジタル放送を受信して、近距離無線通信技術であるブルートゥースを用いて容易に通信することができる。ところが、ブルートゥースの周波数帯が２．４ＧＨｚである一方、デジタル放送はそれと異なる周波数帯を使用する。具体的に、衛星ＤＭＢ（ｄｉｇｉｔａｌ ｍｕｌｔｉｍｅｄｉａ ｂｒｏａｄｃａｓｔｉｎｇ）は、周波数帯が２．６３〜２．６５５ＧＨｚで、地上波ＤＭＢは、周波数帯が１７４〜２４０ＭＨｚと１．４５２〜１．４９２ＧＨｚである。このように、周波数帯が互いに異なるＤＭＢ信号とブルートゥース信号とが同時に用いられるため、従来の携帯端末機では、それぞれのアンテナを具備しなければならない。   That is, in the conventional mobile terminal, in order to transmit and receive a plurality of communication signals having different frequency bands in one mobile terminal, it is necessary to individually provide antennas used in the respective frequency bands. For example, digital broadcasting can be received by one mobile terminal and can be easily communicated using Bluetooth, which is a short-range wireless communication technology. However, while the Bluetooth frequency band is 2.4 GHz, digital broadcasting uses a different frequency band. Specifically, the satellite DMB (digital multimedia broadcasting) has a frequency band of 2.63 to 2.655 GHz, and the terrestrial DMB has a frequency band of 174 to 240 MHz and 1.452 to 1.492 GHz. As described above, since the DMB signal and the Bluetooth signal having different frequency bands are used at the same time, the conventional mobile terminal must be provided with each antenna.

デジタル放送受信アンテナとブルートゥースアンテナとは、携帯端末機に実装の際、それぞれ異なる位置に取付けられる。そのため、製造工程が複雑になり、携帯端末機において実装空間を大きく占めることになる。従って、携帯端末機の小型化が困難である。   The digital broadcast receiving antenna and the Bluetooth antenna are attached to different positions when mounted on the portable terminal. This complicates the manufacturing process and occupies a large mounting space in the portable terminal. Therefore, it is difficult to reduce the size of the portable terminal.

本発明の目的は、互いに異なる複数の周波数帯に用いることができるアンテナ装置を提供することである。また、本発明の他の目的は、一つのアンテナ装置を用いてデジタル放送を受信すると同時に、ブルートゥースが利用可能な装置を提供することである。本発明のさらに他の目的は、このようなアンテナ装置を用いて携帯端末機の実装空間を確保し、さらに携帯端末機を小型化することである。   An object of the present invention is to provide an antenna device that can be used in a plurality of different frequency bands. Another object of the present invention is to provide an apparatus that can use Bluetooth at the same time as receiving digital broadcasting using one antenna apparatus. Still another object of the present invention is to secure a mounting space for a portable terminal using such an antenna device, and further reduce the size of the portable terminal.

上記のような目的を達成するために、本発明に係る携帯端末機の二重帯域アンテナ装置は、第１アンテナ部、第２アンテナ部、及びアンテナ収納部を備える。第２アンテナ部は、第１アンテナ部の上部において第１アンテナ部と一体に形成され、伸長及び収縮が可能である。アンテナ収納部は、第２アンテナ部の収縮の際に収納される空間である。第１アンテナ部は、第１周波数帯に対応する共振周波数を有し、第２アンテナ部は、伸長の際、第２周波数帯に対応する共振周波数を有する。   In order to achieve the above object, a dual band antenna device of a mobile terminal according to the present invention includes a first antenna unit, a second antenna unit, and an antenna storage unit. The second antenna part is formed integrally with the first antenna part at the upper part of the first antenna part, and can be expanded and contracted. The antenna storage portion is a space that is stored when the second antenna portion contracts. The first antenna unit has a resonance frequency corresponding to the first frequency band, and the second antenna unit has a resonance frequency corresponding to the second frequency band when extended.

＜第１実施例＞
図１は、本発明の実施例に係る携帯端末機の二重帯域アンテナ装置が伸長している状態を示した部分断面図である。
図１に示されたように、携帯端末機２００の二重帯域アンテナ装置は、第１アンテナ部２２０、第２アンテナ部２３０、第１給電点２１１、第２給電点２１２、及びアンテナ収納部２１０を含む。 <First embodiment>
FIG. 1 is a partial cross-sectional view illustrating a state where a dual band antenna device of a mobile terminal according to an embodiment of the present invention is extended.
As shown in FIG. 1, the dual band antenna device of the mobile terminal 200 includes a first antenna unit 220, a second antenna unit 230, a first feeding point 211, a second feeding point 212, and an antenna storage unit 210. including.

アンテナ収納部２１０は、携帯端末機２００内部における空き空間である。アンテナ収納部２１０を通じて第１アンテナ部２２０が移動し、第２アンテナ部２３０の収縮の際に内蔵される。   The antenna storage unit 210 is an empty space inside the mobile terminal 200. The first antenna unit 220 moves through the antenna housing unit 210 and is incorporated when the second antenna unit 230 contracts.

本実施例において、第１アンテナ部２２０は、ヘリカルアンテナからなっているが、第１アンテナ部が必ずヘリカルアンテナである必要はない。第１アンテナ部２２０は、両端部に第１接点２２２と第２接点２２３とを備える。第１アンテナ部２２０は、第２アンテナ部２３０の収縮または伸長に関係なくアンテナ収納部２１０の内部に位置する。   In the present embodiment, the first antenna unit 220 includes a helical antenna, but the first antenna unit does not necessarily have to be a helical antenna. The first antenna unit 220 includes a first contact 222 and a second contact 223 at both ends. The first antenna unit 220 is located inside the antenna storage unit 210 regardless of the contraction or expansion of the second antenna unit 230.

また、他の実施例では、アンテナ装置の伸長の際、第１アンテナ部２２０を携帯端末機２００の外部へ突出するようにすることができる。   In another embodiment, the first antenna unit 220 may protrude outside the portable terminal 200 when the antenna device is extended.

第２アンテナ部２３０は、第１アンテナ部２２０と一体に形成される。第２アンテナ部２３０を、携帯端末機２００外部へ伸長し、また携帯端末機２００の内部へ収縮することが可能である。   The second antenna unit 230 is formed integrally with the first antenna unit 220. The second antenna unit 230 can be extended to the outside of the mobile terminal 200 and contracted to the inside of the mobile terminal 200.

第２アンテナ部２３０が携帯端末機２００外部へ伸長する場合には、第１アンテナ部２２０は、第２アンテナ部２３０と一体に形成されているため、携帯端末機２００の上部に移動する。その際、第１接点２２２は第１給電点２１１と接するようになる。   When the second antenna unit 230 extends outside the mobile terminal 200, the first antenna unit 220 is formed integrally with the second antenna unit 230, and thus moves to the upper part of the mobile terminal 200. At that time, the first contact 222 comes into contact with the first feeding point 211.

第１アンテナ部２２０は、第１周波数帯に対応する共振周波数を有し、第２アンテナ部２３０は、第２周波数帯に対応する共振周波数を有する。従って、一つのアンテナ装置を用いて、同時に周波数帯が互いに異なる第１周波数帯と第２周波数帯の信号を送受信することができる。例えば、第１周波数帯は、ブルートゥース信号の周波数帯とし、第２周波数帯は、デジタル放送信号の周波数帯に設定することができる。従って、一つのアンテナ装置を用いて、携帯端末機にデジタル放送信号を受信しながらブルートゥース機能を用いて通信することが可能である。   The first antenna unit 220 has a resonance frequency corresponding to the first frequency band, and the second antenna unit 230 has a resonance frequency corresponding to the second frequency band. Therefore, it is possible to transmit and receive signals in the first frequency band and the second frequency band having different frequency bands at the same time using one antenna device. For example, the first frequency band can be set to the frequency band of the Bluetooth signal, and the second frequency band can be set to the frequency band of the digital broadcast signal. Therefore, it is possible to communicate using the Bluetooth function while receiving a digital broadcast signal to the portable terminal using one antenna device.

図２は、本発明の実施例に係る携帯端末機の二重帯域アンテナ装置が収縮している状態を示した部分断面図である。
第２アンテナ部２３０が、携帯端末機２００内部へ収縮する場合には、第１アンテナ部２２０も携帯端末機２００下部に移動する。その際、第２接点２２３は第２給電点２１２と接するようになる。本実施例においては、第１アンテナ部２２０の下部に突起２２２を形成して安定に接するようになる。 FIG. 2 is a partial cross-sectional view illustrating a contracted state of the dual band antenna device of the mobile terminal according to the embodiment of the present invention.
When the second antenna unit 230 contracts into the mobile terminal 200, the first antenna unit 220 also moves to the lower part of the mobile terminal 200. At that time, the second contact 223 comes into contact with the second feeding point 212. In the present embodiment, a protrusion 222 is formed on the lower portion of the first antenna unit 220 so as to come into stable contact.

第２アンテナ部２３０の収縮により、第２周波数帯に存在する共振周波数がなくなる。しかし、第１アンテナ部２２０は、ただ位置のみを移動しているため、第１周波数帯に存在する共振周波数をそのまま有する。従って、第２アンテナ部２３０の収縮の際には第１周波数帯の信号のみが送受信可能である。   Due to the contraction of the second antenna unit 230, the resonance frequency existing in the second frequency band disappears. However, since the first antenna unit 220 moves only in the position, the first antenna unit 220 has the resonance frequency existing in the first frequency band as it is. Therefore, when the second antenna unit 230 contracts, only signals in the first frequency band can be transmitted and received.

＜第２実施例＞
図３は、本発明の他の実施例に係る携帯端末機の二重帯域アンテナ装置が伸長している状態を示した部分断面図である。
図３に示されたように、携帯端末機３００の二重帯域アンテナ装置は、アンテナ部、第３給電点３１１、第４給電点３１２、アンテナ収納部３１０、及び止め突起３１３を含む。 <Second embodiment>
FIG. 3 is a partial cross-sectional view illustrating a state in which a dual band antenna device of a mobile terminal according to another embodiment of the present invention is extended.
As shown in FIG. 3, the dual band antenna device of the mobile terminal 300 includes an antenna unit, a third feeding point 311, a fourth feeding point 312, an antenna storage unit 310, and a stop protrusion 313.

本実施例において、アンテナ部は、直径の異なる３本のロッドからなっている。アンテナ部は、第３接点３２２と第４接点（図５には、未図示）とを備える。アンテナ部は、携帯端末機３００の外部への伸長や、携帯端末機３００の内部への収縮が可能である。   In the present embodiment, the antenna portion is composed of three rods having different diameters. The antenna unit includes a third contact 322 and a fourth contact (not shown in FIG. 5). The antenna unit can be extended to the outside of the mobile terminal 300 and can be contracted to the inside of the mobile terminal 300.

アンテナ部が携帯端末機３００の外部へ伸長する場合には、第３接点３２２を中心に携帯端末機３００の外部へ突出した部分を第３アンテナ部３３０とし、携帯端末機３００の内部へ突出した部分を第４アンテナ部３２０とする。その際、第３接点３２２は第３給電点３１１に接することになる。   When the antenna unit extends to the outside of the mobile terminal 300, the portion protruding to the outside of the mobile terminal 300 around the third contact 322 serves as the third antenna unit 330 and protrudes to the inside of the mobile terminal 300. The portion is referred to as a fourth antenna unit 320. At that time, the third contact 322 comes into contact with the third feeding point 311.

第３アンテナ部３３０は、第３周波数帯に対応する共振周波数を有し、第４アンテナ部３２０は、第４周波数帯に対応する共振周波数を有する。従って、一つのアンテナ装置を用いて、同時に、周波数帯の異なる第３周波数帯と第４周波数帯との信号を送受信することができる。例えば、第３周波数帯は、デジタル放送信号の周波数帯とし、第４周波数帯は、ブルートゥース信号の周波数帯に設定することができる。従って、一つのアンテナ装置を用いることにより、携帯端末機にデジタル放送信号を受信できるとともにブルートゥース機能を発揮して通信することができる。   The third antenna unit 330 has a resonance frequency corresponding to the third frequency band, and the fourth antenna unit 320 has a resonance frequency corresponding to the fourth frequency band. Therefore, signals of the third frequency band and the fourth frequency band having different frequency bands can be transmitted and received at the same time using one antenna device. For example, the third frequency band can be set to the frequency band of the digital broadcast signal, and the fourth frequency band can be set to the frequency band of the Bluetooth signal. Accordingly, by using a single antenna device, a digital broadcast signal can be received by the mobile terminal, and communication can be performed with a Bluetooth function.

図４は、本発明の他の実施例に係る携帯端末機の二重帯域アンテナ装置が収縮している状態を示す部分断面図である。
アンテナ部が携帯端末機３００内部へ収縮する場合には、最大径ロッドが、アンテナ収納部３１０に挿入され、最大径ロッドの内部に形成されたホールを介して中径ロッドが挿入され、中径ロッドの内部に形成されたホールを介して最小径ロッドが挿入される。最大径ロッドは、アンテナ収納部３１０の内部で第３接点３２２が止め突起３１３に接するようになる。これによって、最大径ロッドはそれ以上挿入されない。 FIG. 4 is a partial cross-sectional view illustrating a contracted state of a dual band antenna device of a mobile terminal according to another embodiment of the present invention.
When the antenna unit contracts into the portable terminal 300, the maximum diameter rod is inserted into the antenna storage unit 310, and the medium diameter rod is inserted through the hole formed inside the maximum diameter rod. The rod with the smallest diameter is inserted through a hole formed inside the rod. In the maximum diameter rod, the third contact 322 comes into contact with the stop protrusion 313 inside the antenna housing part 310. This prevents the maximum diameter rod from being inserted any further.

最小径ロッドは第４接点３２３を含む。第４接点３２３は、アンテナ装置の収縮の際、第４給電点３１２と接する。最小径ロッドは、第４接点３２３を基準に携帯端末機３００の内部方向（収縮方向）へ突出した部分を有する。この部分が第５アンテナ部３４０である。   The smallest diameter rod includes a fourth contact 323. The fourth contact 323 contacts the fourth feeding point 312 when the antenna device contracts. The smallest diameter rod has a portion protruding in the internal direction (contraction direction) of the mobile terminal 300 with respect to the fourth contact 323. This portion is the fifth antenna unit 340.

アンテナ部が収縮する場合には、第３アンテナ部と第４アンテナ部は、共振周波数がなくなり、第５アンテナ部３４０のみが第５周波数帯に対応する共振周波数を有する。従って、アンテナ部が収縮する場合には第５周波数帯の信号のみが送受信可能である。   When the antenna portion contracts, the third antenna portion and the fourth antenna portion have no resonance frequency, and only the fifth antenna portion 340 has a resonance frequency corresponding to the fifth frequency band. Therefore, when the antenna unit contracts, only signals in the fifth frequency band can be transmitted and received.

その際、第４アンテナ部の共振周波数と第５アンテナ部３４０の共振周波数とが等しくなるように、アンテナ部のロッドの長さを調整することができる。   At this time, the length of the rod of the antenna unit can be adjusted so that the resonance frequency of the fourth antenna unit and the resonance frequency of the fifth antenna unit 340 are equal.
